Induction of ovulation with menotropins in women with polycystic ovary syndrome.
Twenty-four women with ovulatory infertility as a result of surgically or biochemically documented polycystic ovary syndrome (PCO) who had failed to conceive during clomiphene citrate therapy underwent a closely supervised menotropin treatment to induce ovulation. Evidence of ovulation was obtained in all patients treated, and major side effects were limited. Fourteen women conceived after an average of 2.4 treatment cycles; twin pregnancies occurred in 36% and spontaneous abortions occurred in 21%. Initial treatment cycles tended to be less successful than the subsequent treatment cycles. Serum 17 beta-estradiol (E2) levels were significantly augmented in the last 3 days before administration of chorionic gonadotropins (hCG) in treatment cycles resulting in conception compared to E2 levels in those cycles which resulted in ovulation only. A second hCG administration to trigger ovulation had to be given in 27% of the treatment cycles and seemed to be an indication of a less promising treatment cycle. Treatment cycles resulting in twin gestations did not differ from those resulting in singleton gestations; specifically, the E2 response was not increased. In summary, under a closely monitored regimen, menotropin therapy can be used in women with nonovulatory infertility as a result of PCO with considerable effectiveness and relative safety once clomiphene citrate treatment has failed.
